BACKGROUND

Delivery of nucleic acids has been explored extensively as a potential therapeutic option for certain disease states. In particular, RNA interference (RNAi) has been the subject of significant research and clinical development. While RNAi, such as short interfering RNA (siRNA), may have therapeutic potential, it is of little use in treating diseases involving deficiency of one or more proteins. messenger RNA (mRNA) therapy has become an increasingly important option for treatment of various diseases, in particular, for those associated with deficiency of one or more proteins.

SUMMARY OF THE INVENTION

The present invention provides improved methods and compositions for highly efficient delivery and expression of mRNA and encoded protein in vivo. The invention is based, in part, on the surprising discovery that liposomes based on a particular class of cationic lipids, such as, those having a structure of formula I-c described herein, are unexpectedly effective in delivering mRNA and producing encoded protein in vivo, more effective even as compared to those cationic lipids that were considered to be among the best in delivering mRNA in the prior art. Indeed, prior to the present invention, cationic lipids have been extensively explored as an important component of liposomes typically used to encapsulate nucleic acids including mRNA for in vivo delivery. Due to the uniquely fragile and long structure of mRNA and the complicated in vivo translation process, cationic lipids used in the liposomes typically play two roles. First, cationic lipids promote interaction with negatively charged mRNA during encapsulation, circulation and endocytosis, thereby capturing and protecting the mRNA. Then, once inside cytosol, cationic lipids need to be able to release the mRNA so that the mRNA can be translated to produce encoded protein. Some cationic lipids, in particular, those known as titratable cationic lipids are particularly effective in delivering mRNA. One example of such cationic lipids known to be capable of efficient delivery of mRNA is C12-200. Surprisingly, the present inventors found that cationic lipids described herein can be even more effective in delivering various mRNA in vivo, than those best known in the prior art including C12-200. For example, as shown in the Examples below, liposome particles incorporating a cationic lipid described herein (e.g., cKK-E12) resulted in close to 50% higher protein expression of human Factor IX protein detected in the plasma of administered mice, as compared to C12-200-based liposome particles. Furthermore, the plasma residence time of different proteins expressed from mRNA delivered by cKK-E12 based liposomes is sustained up to 7 days or longer post a single administration. Thus, the present inventors have demonstrated that this class of cationic lipids having a structure of formula I-c described herein (e.g., cKK-E12) can be uniquely useful in delivering mRNA for highly efficient and sustained production of protein (e.g., therapeutic protein) in vivo. The present invention therefore permits an improved mRNA therapy that can significantly reduce required amount of mRNA and associated lipids, administration frequency, and possible side effects, providing more potent, safer, and patient friendly mRNA therapy for various diseases.

In one aspect, the present invention provides methods of delivering messenger RNA (mRNA) in vivo, including administering to a subject in need of delivery a composition comprising an mRNA encoding a protein, encapsulated within a liposome such that the administering of the composition results in the expression of the protein encoded by the mRNA in vivo, wherein the liposome comprises a cationic lipid of formula I-c:

DEFINITIONS

In order for the present invention to be more readily understood, certain terms are first defined below. Additional definitions for the following terms and other terms are set forth throughout the specification. The publications and other reference materials referenced herein to describe the background of the invention and to provide additional detail regarding its practice are hereby incorporated by reference.

Amino acid: As used herein, term “amino acid,” in its broadest sense, refers to any compound and/or substance that can be incorporated into a polypeptide chain. In some embodiments, an amino acid has the general structure H_(E)N—C(H)(R)—COHO. In some embodiments, an amino acid is a naturally occurring amino acid. In some embodiments, an amino acid is a synthetic amino acid; in some embodiments, an amino acid is a d-amino acid; in some embodiments, an amino acid is an 1-amino acid. “Standard amino acid” refers to any of the twenty standard 1-amino acids commonly found in naturally occurring peptides. “Nonstandard amino acid” refers to any amino acid, other than the standard amino acids, regardless of whether it is prepared synthetically or obtained from a natural source. As used herein, “synthetic amino acid” encompasses chemically modified amino acids, including but not limited to salts, amino acid derivatives (such as amides), and/or substitutions. Amino acids, including carboxyl- and/or amino-terminal amino acids in peptides, can be modified by methylation, amidation, acetylation, protecting groups, and/or substitution with other chemical groups that can change the peptide's circulating half-life without adversely affecting their activity. Amino acids may participate in a disulfide bond. Amino acids may comprise one or posttranslational modifications, such as association with one or more chemical entities (e.g., methyl groups, acetate groups, acetyl groups, phosphate groups, formyl moieties, isoprenoid groups, sulfate groups, polyethylene glycol moieties, lipid moieties, carbohydrate moieties, biotin moieties, etc.). The term “amino acid” is used interchangeably with “amino acid residue,” and may refer to a free amino acid and/or to an amino acid residue of a peptide. It will be apparent from the context in which the term is used whether it refers to a free amino acid or a residue of a peptide.

Animal: As used herein, the term “animal” refers to any member of the animal kingdom. In some embodiments, “animal” refers to humans, at any stage of development. In some embodiments, “animal” refers to non-human animals, at any stage of development. In certain embodiments, the non-human animal is a mammal (e.g., a rodent, a mouse, a rat, a rabbit, a monkey, a dog, a cat, a sheep, cattle, a primate, and/or a pig). In some embodiments, animals include, but are not limited to, mammals, birds, reptiles, amphibians, fish, insects, and/or worms. In some embodiments, an animal may be a transgenic animal, genetically-engineered animal, and/or a clone.

Approximately or about: As used herein, the term “approximately” or “about,” as applied to one or more values of interest, refers to a value that is similar to a stated reference value. In certain embodiments, the term “approximately” or “about” refers to a range of values that fall within 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less in either direction (greater than or less than) of the stated reference value unless otherwise stated or otherwise evident from the context (except where such number would exceed 100% of a possible value).

Delivery: As used herein, the term “delivery” encompasses both local and systemic delivery. For example, delivery of mRNA encompasses situations in which an mRNA is delivered to a target tissue and the encoded protein is expressed and retained within the target tissue (also referred to as “local distribution” or “local delivery”), and situations in which an mRNA is delivered to a target tissue and the encoded protein is expressed and secreted into patient's circulation system (e.g., serum) and systematically distributed and taken up by other tissues (also referred to as “systemic distribution” or “systemic delivery).

Expression: As used herein, “expression” of a nucleic acid sequence refers to translation of an mRNA into a polypeptide, assemble multiple polypeptides (e.g., heavy chain or light chain of antibody) into an intact protein (e.g., antibody) and/or post-translational modification of a polypeptide or fully assembled protein (e.g., antibody). In this application, the terms “expression” and “production,” and grammatical equivalent, are used inter-changeably.

Functional: As used herein, a “functional” biological molecule is a biological molecule in a form in which it exhibits a property and/or activity by which it is characterized.

Half-life: As used herein, the term “half-life” is the time required for a quantity such as nucleic acid or protein concentration or activity to fall to half of its value as measured at the beginning of a time period.

Improve, increase, or reduce: As used herein, the terms “improve,” “increase” or “reduce,” or grammatical equivalents, indicate values that are relative to a baseline measurement, such as a measurement in the same individual prior to initiation of the treatment described herein, or a measurement in a control subject (or multiple control subject) in the absence of the treatment described herein. A “control subject” is a subject afflicted with the same form of disease as the subject being treated, who is about the same age as the subject being treated.

In Vitro: As used herein, the term “in vitro” refers to events that occur in an artificial environment, e.g., in a test tube or reaction vessel, in cell culture, etc., rather than within a multi-cellular organism.

In Vivo: As used herein, the term “in vivo” refers to events that occur within a multi-cellular organism, such as a human and a non-human animal. In the context of cell-based systems, the term may be used to refer to events that occur within a living cell (as opposed to, for example, in vitro systems).

Isolated: As used herein, the term “isolated” refers to a substance and/or entity that has been (1) separated from at least some of the components with which it was associated when initially produced (whether in nature and/or in an experimental setting), and/or (2) produced, prepared, and/or manufactured by the hand of man. Isolated substances and/or entities may be separated from about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more than about 99% of the other components with which they were initially associated. In some embodiments, isolated agents are about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more than about 99% pure. As used herein, a substance is “pure” if it is substantially free of other components. As used herein, calculation of percent purity of isolated substances and/or entities should not include excipients (e.g., buffer, solvent, water, etc.).

Local distribution or delivery: As used herein, the terms “local distribution,” “local delivery,” or grammatical equivalent, refer to tissue specific delivery or distribution. Typically, local distribution or delivery requires a protein (e.g., enzyme) encoded by mRNAs be translated and expressed intracellularly or with limited secretion that avoids entering the patient's circulation system.

messenger RNA (mRNA): As used herein, the term “messenger RNA (mRNA)” refers to a polynucleotide that encodes at least one polypeptide. mRNA as used herein encompasses both modified and unmodified RNA. mRNA may contain one or more coding and non-coding regions. mRNA can be purified from natural sources, produced using recombinant expression systems and optionally purified, chemically synthesized, etc. Where appropriate, e.g., in the case of chemically synthesized molecules, mRNA can comprise nucleoside analogs such as analogs having chemically modified bases or sugars, backbone modifications, etc. An mRNA sequence is presented in the 5′ to 3′ direction unless otherwise indicated. In some embodiments, an mRNA is or comprises natural nucleosides (e.g., adenosine, guanosine, cytidine, uridine); nucleoside analogs (e.g., 2-aminoadenosine, 2-thiothymidine, inosine, pyrrolo-pyrimidine, 3-methyl adenosine, 5-methylcytidine, C-5 propynyl-cytidine, C-5 propynyl-uridine, 2-aminoadenosine, C5-bromouridine, C5-fluorouridine, C5-iodouridine, C5-propynyl-uridine, C5-propynyl-cytidine, C5-methylcytidine, 2-aminoadenosine, 7-deazaadenosine, 7-deazaguanosine, 8-oxoadenosine, 8-oxoguanosine, O(6)-methylguanine, and 2-thiocytidine); chemically modified bases; biologically modified bases (e.g., methylated bases); intercalated bases; modified sugars (e.g., 2′-fluororibose, ribose, 2′-deoxyribose, arabinose, and hexose); and/or modified phosphate groups (e.g., phosphorothioates and 5′-N-phosphoramidite linkages).

In some embodiments, the mRNA comprises one or more nonstandard nucleotide residues. The nonstandard nucleotide residues may include, e.g., 5-methyl-cytidine (“5mC”), pseudouridine (“ψU”), and/or 2-thio-uridine (“2sU”). See, e.g., U.S. Pat. No. 8,278,036 or WO2011012316 for a discussion of such residues and their incorporation into mRNA. The mRNA may be RNA, which is defined as RNA in which 25% of U residues are 2-thio-uridine and 25% of C residues are 5-methylcytidine. Teachings for the use of RNA are disclosed US Patent Publication US20120195936 and internation publication WO2011012316, both of which are hereby incorporated by reference in their entirety. The presence of nonstandard nucleotide residues may render an mRNA more stable and/or less immunogenic than a control mRNA with the same sequence but containing only standard residues. In further embodiments, the mRNA may comprise one or more nonstandard nucleotide residues chosen from isocytosine, pseudoisocytosine, 5-bromouracil, 5-propynyluracil, 6-aminopurine, 2-aminopurine, inosine, diaminopurine and 2-chloro-6-aminopurine cytosine, as well as combinations of these modifications and other nucleobase modifications. Certain embodiments may further include additional modifications to the furanose ring or nucleobase. Additional modifications may include, for example, sugar modifications or substitutions (e.g., one or more of a 2′-O-alkyl modification, a locked nucleic acid (LNA)). In some embodiments, the RNAs may be complexed or hybridized with additional polynucleotides and/or peptide polynucleotides (PNA). In embodiments where the sugar modification is a 2′-O-alkyl modification, such modification may include, but are not limited to a 2′-deoxy-2′-fluoro modification, a 2′-O-methyl modification, a 2′-O-methoxyethyl modification and a 2′-deoxy modification.

Nucleic acid: As used herein, the term “nucleic acid,” in its broadest sense, refers to any compound and/or substance that is or can be incorporated into a polynucleotide chain. In some embodiments, a nucleic acid is a compound and/or substance that is or can be incorporated into a polynucleotide chain via a phosphodiester linkage. In some embodiments, “nucleic acid” refers to individual nucleic acid residues (e.g., nucleotides and/or nucleosides). In some embodiments, “nucleic acid” refers to a polynucleotide chain comprising individual nucleic acid residues. In some embodiments, “nucleic acid” encompasses RNA as well as single and/or double-stranded DNA and/or cDNA.

Patient: As used herein, the term “patient” or “subject” refers to any organism to which a provided composition may be administered, e.g., for experimental, diagnostic, prophylactic, cosmetic, and/or therapeutic purposes. Typical patients include animals (e.g., mammals such as mice, rats, rabbits, non-human primates, and/or humans). In some embodiments, a patient is a human. A human includes pre and post natal forms.

Pharmaceutically acceptable: The term “pharmaceutically acceptable” as used herein, refers to substances that, within the scope of sound medical judgment, are suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

Systemic distribution or delivery: As used herein, the terms “systemic distribution,” “systemic delivery,” or grammatical equivalent, refer to a delivery or distribution mechanism or approach that affect the entire body or an entire organism. Typically, systemic distribution or delivery is accomplished via body's circulation system, e.g., blood stream. Compared to the definition of “local distribution or delivery.”

Subject: As used herein, the term “subject” refers to a human or any non-human animal (e.g., mouse, rat, rabbit, dog, cat, cattle, swine, sheep, horse or primate). A human includes pre- and post-natal forms. In many embodiments, a subject is a human being. A subject can be a patient, which refers to a human presenting to a medical provider for diagnosis or treatment of a disease. The term “subject” is used herein interchangeably with “individual” or “patient.” A subject can be afflicted with or is susceptible to a disease or disorder but may or may not display symptoms of the disease or disorder.

Substantially: As used herein, the term “substantially” refers to the qualitative condition of exhibiting total or near-total extent or degree of a characteristic or property of interest. One of ordinary skill in the biological arts will understand that biological and chemical phenomena rarely, if ever, go to completion and/or proceed to completeness or achieve or avoid an absolute result. The term “substantially” is therefore used herein to capture the potential lack of completeness inherent in many biological and chemical phenomena.

Target tissues: As used herein, the term “target tissues” refers to any tissue that is affected by a disease to be treated. In some embodiments, target tissues include those tissues that display disease-associated pathology, symptom, or feature.

Therapeutically effective amount: As used herein, the term “therapeutically effective amount” of a therapeutic agent means an amount that is sufficient, when administered to a subject suffering from or susceptible to a disease, disorder, and/or condition, to treat, diagnose, prevent, and/or delay the onset of the symptom(s) of the disease, disorder, and/or condition. It will be appreciated by those of ordinary skill in the art that a therapeutically effective amount is typically administered via a dosing regimen comprising at least one unit dose.

Treating: As used herein, the term “treat,” “treatment,” or “treating” refers to any method used to partially or completely alleviate, ameliorate, relieve, inhibit, prevent, delay onset of, reduce severity of and/or reduce incidence of one or more symptoms or features of a particular disease, disorder, and/or condition. Treatment may be administered to a subject who does not exhibit signs of a disease and/or exhibits only early signs of the disease for the purpose of decreasing the risk of developing pathology associated with the disease.

DETAILED DESCRIPTION

The present invention provides, among other things, methods and compositions for delivering mRNA in vivo using improved liposomes incorporating cationic lipids described herein.

Liposomes for mRNA Delivery

As used herein, the term “liposome” refers to any lamellar, multilamellar, or solid lipid nanoparticle vesicle. Typically, a liposome as used herein can be formed by mixing one or more lipids or by mixing one or more lipids and polymer(s). Thus, the term “liposome” as used herein encompasses both lipid and polymer based nanoparticles. In particular, a liposome according to the present invention incorporates a cationic lipid described herein. As a non-limiting example, a cationic lipid suitable for the present invention is cKK-E12, or (3,6-bis(4-(bis(2-hydroxydodecyl)amino)butyl)piperazine-2,5-dione), as described in more detail below. A suitable liposome may also contain second or additional cationic lipids, helper lipids (e.g., non-cationic lipids and/or cholesterol-based lipids), PEG-modified lipids, and/or polymers.

In some embodiments, cationic lipid(s) (e.g., cKK-E12) constitute(s) about 30-50% (e.g., about 30-45%, about 30-40%, about 35-50%, about 35-45%, or about 35-40%) of the liposome by molar ratio. In some embodiments, the cationic lipid (e.g., cKK-E12) constitutes about 30%, about 35%, about 40%, about 45%, or about 50% of the liposome by molar ratio.

In some embodiments, liposomes may comprise a second or additional cationic lipid. As used herein, the phrase “cationic lipid” refers to any of a number of lipid species that have a net positive charge at a selected pH, such as physiological pH. Several cationic lipids have been described in the literature, many of which are commercially available. Particularly suitable cationic lipids for use in the compositions and methods of the invention include those described in international patent publications WO 2010/053572 (and particularly, C12-200 described at paragraph [00225]) and WO 2012/170930, both of which are incorporated herein by reference. In certain embodiments, the compositions and methods of the invention employ a lipid nanoparticles comprising an ionizable cationic lipid described in U.S. provisional patent application 61/617,468, filed Mar. 29, 2012 (incorporated herein by reference), such as, e.g, (15Z,18Z)-N,N-dimethyl-6-(9Z,12Z)-octadeca-9,12-dien-1-yl)tetracosa-15,18-dien-1-amine (HGT5000), (15Z,18Z)-N,N-dimethyl-6-((9Z,12Z)-octadeca-9,12-dien-1-yl)tetracosa-4,15,18-trien-1-amine (HGT5001), and (15Z,18Z)-N,N-dimethyl-6-((9Z,12Z)-octadeca-9,12-dien-1-yl)tetracosa-5,15,18-trien-1-amine (HGT5002).

In some embodiments, the second or additional cationic lipid N-[1-(2,3-dioleyloxy)propyl]-N,N,N-trimethylammonium chloride or “DOTMA” is used. (Feigner et al. (Proc. Nat'l Acad. Sci. 84, 7413 (1987); U.S. Pat. No. 4,897,355). DOTMA can be formulated alone or can be combined with the neutral lipid, dioleoylphosphatidyl-ethanolamine or “DOPE” or other cationic or non-cationic lipids into a liposomal transfer vehicle or a lipid nanoparticle, and such liposomes can be used to enhance the delivery of nucleic acids into target cells.

T. et al. “Lipid-like materials for low-dose in vivo gene silencing” PNAS 2010, 107, 1864-1869).

Non-Cationic/Helper Lipids

In some embodiments, provided liposomes contain one or more non-cationic (“helper”) lipids. As used herein, the phrase “non-cationic lipid” refers to any neutral, zwitterionic or anionic lipid. As used herein, the phrase “anionic lipid” refers to any of a number of lipid species that carry a net negative charge at a selected H, such as physiological pH. Non-cationic lipids include, but are not limited to, distearoylphosphatidylcholine (DSPC), dioleoylphosphatidylcholine (DOPC), dipalmitoylphosphatidylcholine (DPPC), dioleoylphosphatidylglycerol (DOPG), dipalmitoylphosphatidylglycerol (DPPG), dioleoylphosphatidylethanolamine (DOPE), palmitoyloleoylphosphatidylcholine (POPC), palmitoyloleoyl-phosphatidylethanolamine (POPE), dioleoyl-phosphatidylethanolamine 4-(N-maleimidomethyl)-cyclohexane-1-carboxylate (DOPE-mal), dipalmitoyl phosphatidyl ethanolamine (DPPE), dimyristoylphosphoethanolamine (DMPE), distearoyl-phosphatidyl-ethanolamine (DSPE), 16-O-monomethyl PE, 16-O-dimethyl PE, 18-1-trans PE, 1-stearoyl-2-oleoyl-phosphatidyethanolamine (SOPE), or a mixture thereof.

In some embodiments, such non-cationic lipids may be used alone, but are preferably used in combination with other excipients, for example, cationic lipids. In some embodiments, the non-cationic lipid may comprise a molar ratio of about 5% to about 90%, or about 10% to about 70% of the total lipid present in a liposome. In some embodiments, a non-cationic lipid is a neutral lipid, i.e., a lipid that does not carry a net charge in the conditions under which the composition is formulated and/or administered. In some embodiments, the percentage of non-cationic lipid in a liposome may be greater than 5%, greater than 10%, greater than 20%, greater than 30%, or greater than 40%.

Cholesterol-Based Lipids

In some embodiments, provided liposomes comprise one or more cholesterol-based lipids. For example, suitable cholesterol-based cationic lipids include, for example, DC-Choi (N,N-dimethyl-N-ethylcarboxamidocholesterol), 1,4-bis(3-N-oleylamino-propyl)piperazine (Gao, et al. Biochem. Biophys. Res. Comm. 179, 280 (1991); Wolf et al. BioTechniques 23, 139 (1997); U.S. Pat. No. 5,744,335), or ICE. In some embodiments, the cholesterol-based lipid may comprise a molar ration of about 2% to about 30%, or about 5% to about 20% of the total lipid present in a liposome. In some embodiments, The percentage of cholesterol-based lipid in the lipid nanoparticle may be greater than 5, %, 10%, greater than 20%, greater than 30%, or greater than 40%.

PEGylated Lipids

In some embodiments, provided liposomes comprise one or more PEGylated lipids. For example, the use of polyethylene glycol (PEG)-modified phospholipids and derivatized lipids such as derivatized ceramides (PEG-CER), including N-Octanoyl-Sphingosine-1-[Succinyl(Methoxy Polyethylene Glycol)-2000] (C8 PEG-2000 ceramide) is also contemplated by the present invention in combination with one or more of the cationic and, in some embodiments, other lipids together which comprise the liposome. Contemplated PEG-modified lipids include, but are not limited to, a polyethylene glycol chain of up to 5 kDa in length covalently attached to a lipid with alkyl chain(s) of C₆-C₂₀ length. In some embodiments, a PEG-modified or PEGylated lipid is PEGylated cholesterol or PEG-2K. The addition of such components may prevent complex aggregation and may also provide a means for increasing circulation lifetime and increasing the delivery of the lipid-nucleic acid composition to the target cell, (Klibanov et al. (1990) FEBS Letters, 268 (1): 235-237), or they may be selected to rapidly exchange out of the formulation in vivo (see U.S. Pat. No. 5,885,613).

In some embodiments, particularly useful exchangeable lipids are PEG-ceramides having shorter acyl chains (e.g., C₁₄ or C₁₈). The PEG-modified phospholipid and derivitized lipids of the present invention may comprise a molar ratio from about 0% to about 15%, about 0.5% to about 15%, about 1% to about 15%, about 4% to about 10%, or about 2% of the total lipid present in the liposome.

According to various embodiments, the selection of second or additional cationic lipids, non-cationic lipids and/or PEG-modified lipids which comprise the lipid nanoparticle, as well as the relative molar ratio of such lipids to each other, is based upon the characteristics of the selected lipid(s), the nature of the intended target cells, the characteristics of the mRNA to be delivered. Additional considerations include, for example, the saturation of the alkyl chain, as well as the size, charge, pH, pKa, fusogenicity and toxicity of the selected lipid(s). Thus the molar ratios may be adjusted accordingly. In some embodiments, the percentage of PEG-modified lipid in a liposome may be greater than 1%, greater than 2%, greater than 5%, greater than 10%, or greater than 15%.

Polymer

In some embodiments, a suitable liposome according to the present invention further includes a polymer, in combination with one or more cationic lipids as described and, in some embodiments, other carriers including various lipids described herein. Thus, in some embodiments, liposomal delivery vehicles, as used herein, also encompass polymer containing nanoparticles. Suitable polymers may include, for example, polyacrylates, polyalkycyanoacrylates, polylactide, polylactide-polyglycolide copolymers, polycaprolactones, dextran, albumin, gelatin, alginate, collagen, chitosan, cyclodextrins, protamine, PEGylated protamine, PLL, PEGylated PLL and polyethylenimine (PEI). When PEI is present, it may be branched PEI of a molecular weight ranging from 10 to 40 kDA, e.g., 25 kDa branched PEI (Sigma #408727).

In some embodiments, a suitable liposome formulation contains a combination of one or more cationic lipids, one or more non-cationic lipids, one or more cholesterol-based lipids one or more PEG-modified lipids, and/or one or more polymers. As a non-limiting example, a suitable liposome comprises cKK-E12, DOPE, cholesterol and DMG-PEG2K. In some embodiments, the ratio of cationic lipid to non-cationic lipid to cholesterol-based lipid to PEGylated lipid may be between about 30-50:25-35:20-30:1-15, respectively. In some embodiments, the ratio of cationic lipid to non-cationic lipid to cholesterol-based lipid to PEGylated lipid is approximately 40:30:20:10, respectively. In some embodiments, the ratio of cationic lipid to non-cationic lipid to cholesterol-based lipid to PEGylated lipid is approximately 40:30:25:5, respectively. In some embodiments, the ratio of cationic lipid to non-cationic lipid to cholesterol-based lipid to PEGylated lipid is approximately 40:32:25:3, respectively.

mRNA

The present invention can be used to deliver any mRNA. mRNA is typically thought of as the type of RNA that carries information from DNA to the ribosome. The existence of mRNA is usually very brief and includes processing and translation, followed by degradation. Typically, in eukaryotic organisms, mRNA processing comprises the addition of a “cap” on the N-terminal (5′) end, and a “tail” on the C-terminal (3′) end. A typical cap is a 7-methylguanosine cap, which is a guanosine that is linked through a 5′-5′-triphosphate bond to the first transcribed nucleotide. The presence of the cap is important in providing resistance to nucleases found in most eukaryotic cells. The tail is typically a polyadenylation event whereby a polyadenylyl moiety is added to the 3′ end of the mRNA molecule. The presence of this “tail” serves to protect the mRNA from exonuclease degradation. Messenger RNA typically is translated by the ribosomes into a series of amino acids that make up a protein.

Any mRNA capable of being translated into one or more peptides (e.g., proteins) or peptide fragments is contemplated as within the scope of the present invention. In some embodiments, an mRNA encodes one or more naturally occurring peptides. In some embodiments, an mRNA encodes one or more modified or non-natural peptides.

In some embodiments an mRNA encodes an intracellular protein. In some embodiments, an mRNA encodes a cytosolic protein. In some embodiments, an mRNA encodes a protein associated with the actin cytoskeleton. In some embodiments, an mRNA encodes a protein associated with the plasma membrane. In some specific embodiments, an mRNA encodes a transmembrane protein. In some specific embodiments an mRNA encodes an ion channel protein. In some embodiments, an mRNA encodes a perinuclear protein. In some embodiments, an mRNA encodes a nuclear protein. In some specific embodiments, an mRNA encodes a transcription factor. In some embodiments, an mRNA encodes a chaperone protein. In some embodiments, an mRNA encodes an intracellular enzyme (e.g., mRNA encoding an enzyme associated with urea cycle or lysosomal storage metabolic disorders). In some embodiments, an mRNA encodes a protein involved in cellular metabolism, DNA repair, transcription and/or translation. In some embodiments, an mRNA encodes an extracellular protein. In some embodiments, an mRNA encodes a protein associated with the extracellular matrix. In some embodiments an mRNA encodes a secreted protein. In specific embodiments, an mRNA used in the composition and methods of the invention may be used to express functional proteins or enzymes that are excreted or secreted by one or more target cells into the surrounding extracellular fluid (e.g., mRNA encoding hormones and/or neurotransmitters).

In some embodiments, the compositions and methods of the invention provide for delivery of mRNA encoding a secreted protein. In some embodiments, the compositions and methods of the invention provide for delivery of mRNA encoding one or more secreted proteins listed in Table 1; thus, compositions of the invention may comprise an mRNA encoding a protein listed in Table 1 (or a homolog thereof) along with other components set out herein, and methods of the invention may comprise preparing and/or administering a composition comprising an mRNA encoding a protein listed in Table 1 (or a homolog thereof) along with other components set out herein.

In some embodiments, the present invention is used to prevent, treat and/or cure a subject affected with a disease or disorder listed or associated with the proteins listed in Tables 1, 2, 3 or 4. In some embodiments, an mRNA encodes one or more of argininosuccinate synthetase (ASS1), Factor IX, survival motor neuron 1 (SMN1), or phenylalanine hydroxylase

Synthesis of mRNA

mRNAs according to the present invention may be synthesized according to any of a variety of known methods. For example, mRNAs according to the present invention may be synthesized via in vitro transcription (IVT). Briefly, IVT is typically performed with a linear or circular DNA template containing a promoter, a pool of ribonucleotide triphosphates, a buffer system that may include DTT and magnesium ions, and an appropriate RNA polymerase (e.g., T3, T7 or SP6 RNA polymerase), DNAse I, pyrophosphatase, and/or RNAse inhibitor. The exact conditions will vary according to the specific application.

In some embodiments, for the preparation of mRNA according to the invention, a DNA template is transcribed in vitro. A suitable DNA template typically has a promoter, for example a T3, T7 or SP6 promoter, for in vitro transcription, followed by desired nucleotide sequence for desired mRNA and a termination signal.

Desired mRNA sequence(s) according to the invention may be determined and incorporated into a DNA template using standard methods. For example, starting from a desired amino acid sequence (e.g., an enzyme sequence), a virtual reverse translation is carried out based on the degenerated genetic code. Optimization algorithms may then be used for selection of suitable codons. Typically, the G/C content can be optimized to achieve the highest possible G/C content on one hand, taking into the best possible account the frequency of the tRNAs according to codon usage on the other hand. The optimized RNA sequence can be established and displayed, for example, with the aid of an appropriate display device and compared with the original (wild-type) sequence. A secondary structure can also be analyzed to calculate stabilizing and destabilizing properties or, respectively, regions of the RNA.

Modified mRNA

In some embodiments, mRNA according to the present invention may be synthesized as unmodified or modified mRNA. Typically, mRNAs are modified to enhance stability. Modifications of mRNA can include, for example, modifications of the nucleotides of the RNA. An modified mRNA according to the invention can thus include, for example, backbone modifications, sugar modifications or base modifications. In some embodiments, mRNAs may be synthesized from naturally occurring nucleotides and/or nucleotide analogues (modified nucleotides) including, but not limited to, purines (adenine (A), guanine (G)) or pyrimidines (thymine (T), cytosine (C), uracil (U)), and as modified nucleotides analogues or derivatives of purines and pyrimidines, such as e.g. 1-methyl-adenine, 2-methyl-adenine, 2-methylthio-N-6-isopentenyl-adenine, N6-methyl-adenine, N6-isopentenyl-adenine, 2-thio-cytosine, 3-methyl-cytosine, 4-acetyl-cytosine, 5-methyl-cytosine, 2,6-diaminopurine, 1-methyl-guanine, 2-methyl-guanine, 2,2-dimethyl-guanine, 7-methyl-guanine, inosine, 1-methyl-inosine, pseudouracil (5-uracil), dihydro-uracil, 2-thio-uracil, 4-thio-uracil, 5-carboxymethylaminomethyl-2-thio-uracil, 5-(carboxyhydroxymethyl)-uracil, 5-fluoro-uracil, 5-bromo-uracil, 5-carboxymethylaminomethyl-uracil, 5-methyl-2-thio-uracil, 5-methyl-uracil, N-uracil-5-oxyacetic acid methyl ester, 5-methylaminomethyl-uracil, 5-methoxyaminomethyl-2-thio-uracil, 5′-methoxycarbonylmethyl-uracil, 5-methoxy-uracil, uracil-5-oxyacetic acid methyl ester, uracil-5-oxyacetic acid (v), 1-methyl-pseudouracil, queosine, .beta.-D-mannosyl-queosine, wybutoxosine, and phosphoramidates, phosphorothioates, peptide nucleotides, methylphosphonates, 7-deazaguanosine, 5-methylcytosine and inosine. The preparation of such analogues is known to a person skilled in the art e.g. from the U.S. Pat. Nos. 4,373,071, 4,401,796, 4,415,732, 4,458,066, 4,500,707, 4,668,777, 4,973,679, 5,047,524, 5,132,418, 5,153,319, 5,262,530 and 5,700,642, the disclosures of which are incorporated by reference in their entirety.

In some embodiments, mRNAs (e.g., enzyme encoding mRNAs) may contain RNA backbone modifications. Typically, a backbone modification is a modification in which the phosphates of the backbone of the nucleotides contained in the RNA are modified chemically. Exemplary backbone modifications typically include, but are not limited to, modifications from the group consisting of methylphosphonates, methylphosphoramidates, phosphoramidates, phosphorothioates (e.g. cytidine 5′-O-(1-thiophosphate)), boranophosphates, positively charged guanidinium groups etc., which means by replacing the phosphodiester linkage by other anionic, cationic or neutral groups.

In some embodiments, mRNAs (e.g., enzyme encoding mRNAs) may contain sugar modifications. A typical sugar modification is a chemical modification of the sugar of the nucleotides it contains including, but not limited to, sugar modifications chosen from the group consisting of 2′-deoxy-2′-fluoro-oligoribonucleotide (2′-fluoro-2′-deoxycytidine 5′-triphosphate, 2′-fluoro-2′-deoxyuridine 5′-triphosphate), 2′-deoxy-2′-deamine-oligoribonucleotide (2′-amino-2′-deoxycytidine 5′-triphosphate, 2′-amino-2′-deoxyuridine 5′-triphosphate), 2′-O-alkyloligoribonucleotide, 2′-deoxy-2′-C-alkyloligoribonucleotide (2′-O-methylcytidine 5′-triphosphate, 2′-methyluridine 5′-triphosphate), 2′-C-alkyloligoribonucleotide, and isomers thereof (2′-aracytidine 5′-triphosphate, 2′-arauridine 5′-triphosphate), or azidotriphosphates (2′-azido-2′-deoxycytidine 5′-triphosphate, 2′-azido-2′-deoxyuridine 5′-triphosphate).

In some embodiments, mRNAs (e.g., enzyme encoding mRNAs) may contain modifications of the bases of the nucleotides (base modifications). A modified nucleotide which contains a base modification is also called a base-modified nucleotide. Examples of such base-modified nucleotides include, but are not limited to, 2-amino-6-chloropurine riboside 5′-triphosphate, 2-aminoadenosine 5′-triphosphate, 2-thiocytidine 5′-triphosphate, 2-thiouridine 5′-triphosphate, 4-thiouridine 5′-triphosphate, 5-aminoallylcytidine 5′-triphosphate, 5-aminoallyluridine 5′-triphosphate, 5-bromocytidine 5′-triphosphate, 5-bromouridine 5′-triphosphate, 5-iodocytidine 5′-triphosphate, 5-iodouridine 5′-triphosphate, 5-methylcytidine 5′-triphosphate, 5-methyluridine 5′-triphosphate, 6-azacytidine 5′-triphosphate, 6-azauridine 5′-triphosphate, 6-chloropurine riboside 5′-triphosphate, 7-deazaadenosine 5′-triphosphate, 7-deazaguanosine 5′-triphosphate, 8-azaadenosine 5′-triphosphate, 8-azidoadenosine 5′-triphosphate, benzimidazole riboside 5′-triphosphate, N1-methyladenosine 5′-triphosphate, N1-methylguanosine 5′-triphosphate, N6-methyladenosine 5′-triphosphate, 06-methylguanosine 5′-triphosphate, pseudouridine 5′-triphosphate, puromycin 5′-triphosphate or xanthosine 5′-triphosphate.

Cap Structure

Typically, mRNA synthesis includes the addition of a “cap” on the N-terminal (5′) end, and a “tail” on the C-terminal (3′) end. The presence of the cap is important in providing resistance to nucleases found in most eukaryotic cells. The presence of a “tail” serves to protect the mRNA from exonuclease degradation.

Thus, in some embodiments, mRNAs (e.g., enzyme encoding mRNAs) include a 5′ cap structure. A 5′ cap is typically added as follows: first, an RNA terminal phosphatase removes one of the terminal phosphate groups from the 5′ nucleotide, leaving two terminal phosphates; guanosine triphosphate (GTP) is then added to the terminal phosphates via a guanylyl transferase, producing a 5′5′5 triphosphate linkage; and the 7-nitrogen of guanine is then methylated by a methyltransferase. Examples of cap structures include, but are not limited to, m7G(5′)ppp (5′(A,G(5′)ppp(5′)A and G(5′)ppp(5′)G.

In some embodiments, naturally occurring cap structures comprise a 7-methyl guanosine that is linked via a triphosphate bridge to the 5′-end of the first transcribed nucleotide, resulting in a dinucleotide cap of m⁷G(5′)ppp(5′)N, where N is any nucleoside. In vivo, the cap is added enzymatically. The cap is added in the nucleus and is catalyzed by the enzyme guanylyl transferase. The addition of the cap to the 5′ terminal end of RNA occurs immediately after initiation of transcription. The terminal nucleoside is typically a guanosine, and is in the reverse orientation to all the other nucleotides, i.e., G(5′)ppp(5′)GpNpNp.

A common cap for mRNA produced by in vitro transcription is m⁷G(5′)ppp(5′)G, which has been used as the dinucleotide cap in transcription with T7 or SP6 RNA polymerase in vitro to obtain RNAs having a cap structure in their 5′-termini. The prevailing method for the in vitro synthesis of capped mRNA employs a pre-formed dinucleotide of the form m⁷G(5′)ppp(5′)G (“m⁷GpppG”) as an initiator of transcription.

To date, a usual form of a synthetic dinucleotide cap used in in vitro translation experiments is the Anti-Reverse Cap Analog (“ARCA”) or modified ARCA, which is generally a modified cap analog in which the 2′ or 3′ OH group is replaced with —OCH₃.

Additional cap analogs include, but are not limited to, chemical structures selected from the group consisting of m⁷GpppG, m⁷GpppA, m⁷GpppC; unmethylated cap analogs (e.g., GpppG); dimethylated cap analog (e.g., m^(2,7)GpppG), trimethylated cap analog (e.g., m^(2,2,7)Gppp), dimethylated symmetrical cap analogs (e.g., m⁷Gpppm⁷G), or anti reverse cap analogs (e.g., ARCA; m⁷, ^(2′Ome)GpppG, m^(72′d)GpppG, m^(7,3′Ome)GpppG, m^(7,3′d)GpppG and their tetraphosphate derivatives) (see, e.g., Jemielity, J. et al., “Novel ‘anti-reverse’ cap analogs with superior translational properties”, RNA, 9: 1108-1122 (2003)).

In some embodiments, a suitable cap is a 7-methyl guanylate (“m⁷G”) linked via a triphosphate bridge to the 5′-end of the first transcribed nucleotide, resulting in m⁷G(5′)ppp(5′)N, where N is any nucleoside. A preferred embodiment of a m⁷G cap utilized in embodiments of the invention is m⁷G(5′)ppp(5′)G.

In some embodiments, the cap is a Cap0 structure. Cap0 structures lack a 2′-O-methyl residue of the ribose attached to bases 1 and 2. In some embodiments, the cap is a Cap1 structure. Cap1 structures have a 2′-O-methyl residue at base 2. In some embodiments, the cap is a Cap2 structure. Cap2 structures have a 2′-O-methyl residue attached to both bases 2 and 3.

A variety of m⁷G cap analogs are known in the art, many of which are commercially available. These include the m⁷GpppG described above, as well as the ARCA 3′-OCH₃ and 2′-OCH₃ cap analogs (Jemielity, J. et al., RNA, 9: 1108-1122 (2003)). Additional cap analogs for use in embodiments of the invention include N7-benzylated dinucleoside tetraphosphate analogs (described in Grudzien, E. et al., RNA, 10: 1479-1487 (2004)), phosphorothioate cap analogs (described in Grudzien-Nogalska, E., et al., RNA, 13: 1745-1755 (2007)), and cap analogs (including biotinylated cap analogs) described in U.S. Pat. Nos. 8,093,367 and 8,304,529, incorporated by reference herein.

Tail Structure

Typically, the presence of a “tail” serves to protect the mRNA from exonuclease degradation. The poly A tail is thought to stabilize natural messengers and synthetic sense RNA. Therefore, in certain embodiments a long poly A tail can be added to an mRNA molecule thus rendering the RNA more stable. Poly A tails can be added using a variety of art-recognized techniques. For example, long poly A tails can be added to synthetic or in vitro transcribed RNA using poly A polymerase (Yokoe, et al. Nature Biotechnology. 1996; 14: 1252-1256). A transcription vector can also encode long poly A tails. In addition, poly A tails can be added by transcription directly from PCR products. Poly A may also be ligated to the 3′ end of a sense RNA with RNA ligase (see, e.g., Molecular Cloning A Laboratory Manual, 2nd Ed., ed. by Sambrook, Fritsch and Maniatis (Cold Spring Harbor Laboratory Press: 1991 edition)).

In some embodiments, mRNAs (e.g., enzyme encoding mRNAs) include a 3′ poly(A) tail structure. Typically, the length of the poly A tail can be at least about 10, 50, 100, 200, 300, 400 at least 500 nucleotides (SEQ ID NO: 12). In some embodiments, a poly-A tail on the 3′ terminus of mRNA typically includes about 10 to 300 adenosine nucleotides (SEQ ID NO: 13) (e.g., about 10 to 200 adenosine nucleotides, about 10 to 150 adenosine nucleotides, about 10 to 100 adenosine nucleotides, about 20 to 70 adenosine nucleotides, or about 20 to 60 adenosine nucleotides). In some embodiments, mRNAs include a 3′ poly(C) tail structure. A suitable poly-C tail on the 3′ terminus of mRNA typically include about 10 to 200 cytosine nucleotides (SEQ ID NO: 14) (e.g., about 10 to 150 cytosine nucleotides, about 10 to 100 cytosine nucleotides, about 20 to 70 cytosine nucleotides, about 20 to 60 cytosine nucleotides, or about 10 to 40 cytosine nucleotides). The poly-C tail may be added to the poly-A tail or may substitute the poly-A tail.

In some embodiments, the length of the poly A or poly C tail is adjusted to control the stability of a modified sense mRNA molecule of the invention and, thus, the transcription of protein. For example, since the length of the poly A tail can influence the half-life of a sense mRNA molecule, the length of the poly A tail can be adjusted to modify the level of resistance of the mRNA to nucleases and thereby control the time course of polynucleotide expression and/or polypeptide production in a target cell.

5′ and 3′ Untranslated Region

In some embodiments, mRNAs include a 5′ and/or 3′ untranslated region. In some embodiments, a 5′ untranslated region includes one or more elements that affect an mRNA's stability or translation, for example, an iron responsive element. In some embodiments, a 5′ untranslated region may be between about 50 and 500 nucleotides in length.

In some embodiments, a 3′ untranslated region includes one or more of a polyadenylation signal, a binding site for proteins that affect an mRNA's stability of location in a cell, or one or more binding sites for miRNAs. In some embodiments, a 3′ untranslated region may be between 50 and 500 nucleotides in length or longer.

Exemplary 3′ and/or 5′ UTR sequences can be derived from mRNA molecules which are stable (e.g., globin, actin, GAPDH, tubulin, histone, or citric acid cycle enzymes) to increase the stability of the sense mRNA molecule. For example, a 5′ UTR sequence may include a partial sequence of a CMV immediate-early 1 (IE1) gene, or a fragment thereof to improve the nuclease resistance and/or improve the half-life of the polynucleotide. Also contemplated is the inclusion of a sequence encoding human growth hormone (hGH), or a fragment thereof to the 3′ end or untranslated region of the polynucleotide (e.g., mRNA) to further stabilize the polynucleotide. Generally, these modifications improve the stability and/or pharmacokinetic properties (e.g., half-life) of the polynucleotide relative to their unmodified counterparts, and include, for example modifications made to improve such polynucleotides' resistance to in vivo nuclease digestion.

According to various embodiments, any size mRNA may be encapsulated by provided liposomes. In some embodiments, the provided liposomes may encapsulate mRNA of greater than about 0.5 kb, 1 kb, 1.5 kb, 2 kb, 2.5 kb, 3 kb, 3.5 kb, 4 kb, 4.5 kb, or 5 kb in length.

Formation of Liposomes

The liposomes for use in provided compositions can be prepared by various techniques which are presently known in the art. For example, multilamellar vesicles (MLV) may be prepared according to conventional techniques, such as by depositing a selected lipid on the inside wall of a suitable container or vessel by dissolving the lipid in an appropriate solvent, and then evaporating the solvent to leave a thin film on the inside of the vessel or by spray drying. An aqueous phase may then added to the vessel with a vortexing motion which results in the formation of MLVs. Uni-lamellar vesicles (ULV) can then be formed by homogenization, sonication or extrusion of the multi-lamellar vesicles. In addition, unilamellar vesicles can be formed by detergent removal techniques.

In certain embodiments, provided compositions comprise a liposome wherein the mRNA is associated on both the surface of the liposome and encapsulated within the same liposome. For example, during preparation of the compositions of the present invention, cationic liposomes may associate with the mRNA through electrostatic interactions. For example, during preparation of the compositions of the present invention, cationic liposomes may associate with the mRNA through electrostatic interactions.

In some embodiments, the compositions and methods of the invention comprise mRNA encapsulated in a liposome. In some embodiments, the one or more mRNA species may be encapsulated in the same liposome. In some embodiments, the one or more mRNA species may be encapsulated in different liposomes. In some embodiments, the mRNA is encapsulated in one or more liposomes, which differ in their lipid composition, molar ratio of lipid components, size, charge (Zeta potential), targeting ligands and/or combinations thereof. In some embodiments, the one or more liposome may have a different composition of cationic lipids, neutral lipid, PEG-modified lipid and/or combinations thereof. In some embodiments the one or more lipisomes may have a different molar ratio of cationic lipid, neutral lipid, cholesterol and PEG-modified lipid used to create the liposome.

The process of incorporation of a desired mRNA into a liposome is often referred to as “loading”. Exemplary methods are described in Lasic, et al., FEBS Lett., 312: 255-258, 1992, which is incorporated herein by reference. The liposome-incorporated nucleic acids may be completely or partially located in the interior space of the liposome, within the bilayer membrane of the liposome, or associated with the exterior surface of the liposome membrane. The incorporation of a nucleic acid into liposomes is also referred to herein as “encapsulation” wherein the nucleic acid is entirely contained within the interior space of the liposome. The purpose of incorporating a mRNA into a transfer vehicle, such as a liposome, is often to protect the nucleic acid from an environment which may contain enzymes or chemicals that degrade nucleic acids and/or systems or receptors that cause the rapid excretion of the nucleic acids. Accordingly, in some embodiments, a suitable delivery vehicle is capable of enhancing the stability of the mRNA contained therein and/or facilitate the delivery of mRNA to the target cell or tissue.

Liposome Size

Suitable liposomes in accordance with the present invention may be made in various sizes. In some embodiments, provided liposomes may be made smaller than previously known mRNA encapsulating liposomes. In some embodiments, decreased size of liposomes is associated with more efficient delivery of mRNA. Selection of an appropriate liposome size may take into consideration the site of the target cell or tissue and to some extent the application for which the liposome is being made.

In some embodiments, an appropriate size of liposome is selected to facilitate systemic distribution of antibody encoded by the mRNA. In some embodiments, it may be desirable to limit transfection of the mRNA to certain cells or tissues. For example, to target hepatocytes a liposome may be sized such that its dimensions are smaller than the fenestrations of the endothelial layer lining hepatic sinusoids in the liver; in such cases the liposome could readily penetrate such endothelial fenestrations to reach the target hepatocytes.

Alternatively or additionally, a liposome may be sized such that the dimensions of the liposome are of a sufficient diameter to limit or expressly avoid distribution into certain cells or tissues. For example, a liposome may be sized such that its dimensions are larger than the fenestrations of the endothelial layer lining hepatic sinusoids to thereby limit distribution of the liposomes to hepatocytes.

In some embodiments, the size of a liposome is determined by the length of the largest diameter of the lipososme particle. In some embodiments, a suitable liposome has a size of or less than about 500 nm, 450 nm, 400 nm, 350 nm, 300 nm, 250 nm, 200 nm, 150 nm, 125 nm, 110 nm, 100 nm, 95 nm, 90 nm, 85 nm, 80 nm, 75 nm, 70 nm, 65 nm, 60 nm, 55 nm, or 50 nm. In some embodiments, a suitable liposome has a size no greater than about 250 nm (e.g., no greater than about 225 nm, 200 nm, 175 nm, 150 nm, 125 nm, 100 nm, 75 nm, or 50 nm). In some embodiments, a suitable liposome has a size ranging from about 10-250 nm (e.g., ranging from about 10-225 nm, 10-200 nm, 10-175 nm, 10-150 nm, 10-125 nm, 10-100 nm, 10-75 nm, or 10-50 nm). In some embodiments, a suitable liposome has a size ranging from about 100-250 nm (e.g., ranging from about 100-225 nm, 100-200 nm, 100-175 nm, 100-150 nm). In some embodiments, a suitable liposome has a size ranging from about 10-100 nm (e.g., ranging from about 10-90 nm, 10-80 nm, 10-70 nm, 10-60 nm, or 10-50 nm).

A variety of alternative methods known in the art are available for sizing of a population of liposomes. One such sizing method is described in U.S. Pat. No. 4,737,323, incorporated herein by reference. Sonicating a liposome suspension either by bath or probe sonication produces a progressive size reduction down to small ULV less than about 0.05 microns in diameter. Homogenization is another method that relies on shearing energy to fragment large liposomes into smaller ones. In a typical homogenization procedure, MLV are recirculated through a standard emulsion homogenizer until selected liposome sizes, typically between about 0.1 and 0.5 microns, are observed. The size of the liposomes may be determined by quasi-electric light scattering (QELS) as described in Bloomfield, Ann. Rev. Biophys. Bioeng., 10:421-150 (1981), incorporated herein by reference. Average liposome diameter may be reduced by sonication of formed liposomes. Intermittent sonication cycles may be alternated with QELS assessment to guide efficient liposome synthesis.

Pharmaceutical Compositions

To facilitate expression of mRNA in vivo, delivery vehicles such as liposomes can be formulated in combination with one or more additional nucleic acids, carriers, targeting ligands or stabilizing reagents, or in pharmacological compositions where it is mixed with suitable excipients. Techniques for formulation and administration of drugs may be found in “Remington's Pharmaceutical Sciences,” Mack Publishing Co., Easton, Pa., latest edition.

Provided liposomally-encapsulated or associated mRNAs, and compositions containing the same, may be administered and dosed in accordance with current medical practice, taking into account the clinical condition of the subject, the site and method of administration, the scheduling of administration, the subject's age, sex, body weight and other factors relevant to clinicians of ordinary skill in the art. The “effective amount” for the purposes herein may be determined by such relevant considerations as are known to those of ordinary skill in experimental clinical research, pharmacological, clinical and medical arts. In some embodiments, the amount administered is effective to achieve at least some stabilization, improvement or elimination of symptoms and other indicators as are selected as appropriate measures of disease progress, regression or improvement by those of skill in the art. For example, a suitable amount and dosing regimen is one that causes at least transient protein (e.g., enzyme) production.

Suitable routes of administration include, for example, oral, rectal, vaginal, transmucosal, pulmonary including intratracheal or inhaled, or intestinal administration; parenteral delivery, including intradermal, transdermal (topical), intramuscular, subcutaneous, intramedullary injections, as well as intrathecal, direct intraventricular, intravenous, intraperitoneal, and/or intranasal administration.

Alternately or additionally, liposomally encapsulated mRNAs and compositions of the invention may be administered in a local rather than systemic manner, for example, via injection of the pharmaceutical composition directly into a targeted tissue, preferably in a sustained release formulation. Local delivery can be affected in various ways, depending on the tissue to be targeted. For example, aerosols containing compositions of the present invention can be inhaled (for nasal, tracheal, or bronchial delivery); compositions of the present invention can be injected into the site of injury, disease manifestation, or pain, for example; compositions can be provided in lozenges for oral, tracheal, or esophageal application; can be supplied in liquid, tablet or capsule form for administration to the stomach or intestines, can be supplied in suppository form for rectal or vaginal application; or can even be delivered to the eye by use of creams, drops, or even injection. Formulations containing provided compositions complexed with therapeutic molecules or ligands can even be surgically administered, for example in association with a polymer or other structure or substance that can allow the compositions to diffuse from the site of implantation to surrounding cells. Alternatively, they can be applied surgically without the use of polymers or supports.

In some embodiments, provided liposomes and/or compositions are formulated such that they are suitable for extended-release of the mRNA contained therein. Such extended-release compositions may be conveniently administered to a subject at extended dosing intervals. For example, in one embodiment, the compositions of the present invention are administered to a subject twice day, daily or every other day. In a preferred embodiment, the compositions of the present invention are administered to a subject twice a week, once a week, every ten days, every two weeks, every three weeks, or more preferably every four weeks, once a month, every six weeks, every eight weeks, every other month, every three months, every four months, every six months, every eight months, every nine months or annually. Also contemplated are compositions and liposomes which are formulated for depot administration (e.g., intramuscularly, subcutaneously, intravitreally) to either deliver or release a mRNA over extended periods of time. Preferably, the extended-release means employed are combined with modifications made to the mRNA to enhance stability.

Also contemplated herein are lyophilized pharmaceutical compositions comprising one or more of the liposomes disclosed herein and related methods for the use of such compositions as disclosed for example, in U.S. Provisional Application No. 61/494,882, filed Jun. 8, 2011, the teachings of which are incorporated herein by reference in their entirety. For example, lyophilized pharmaceutical compositions according to the invention may be reconstituted prior to administration or can be reconstituted in vivo. For example, a lyophilized pharmaceutical composition can be formulated in an appropriate dosage form (e.g., an intradermal dosage form such as a disk, rod or membrane) and administered such that the dosage form is rehydrated over time in vivo by the individual's bodily fluids.

Provided liposomes and compositions may be administered to any desired tissue. In some embodiments, the mRNA delivered by provided liposomes or compositions is expressed in the tissue in which the liposomes and/or compositions were administered. In some embodiments, the mRNA delivered is expressed in a tissue different from the tissue in which the liposomes and/or compositions were administered Exemplary tissues in which delivered mRNA may be delivered and/or expressed include, but are not limited to the liver, kidney, heart, spleen, serum, brain, skeletal muscle, lymph nodes, skin, and/or cerebrospinal fluid.

According to various embodiments, the timing of expression of delivered mRNAs can be tuned to suit a particular medical need. In some embodiments, the expression of the protein encoded by delivered mRNA is detectable 1, 2, 3, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, and/or 72 hours in serum or target tissues after a single administration of provided liposomes or compositions. In some embodiments, the expression of the protein encoded by the mRNA is detectable 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, and/or 7 days in serum or target tissues after a single administration of provided liposomes or compositions. In some embodiments, the expression of the protein encoded by the mRNA is detectable 1 week, 2 weeks, 3 weeks, and/or 4 weeks in serum or target tissues after a single administration of provided liposomes or compositions. In some embodiments, the expression of the protein encoded by the mRNA is detectable after a month or longer after a single administration of provided liposomes or compositions.

The present invention can be used to deliver mRNA at various doses. In some embodiments, an mRNA is administered at a dose ranging from about 0.1-5.0 mg/kg body weight, for example about 0.1-4.5, 0.1-4.0, 0.1-3.5, 0.1-3.0, 0.1-2.5, 0.1-2.0, 0.1-1.5, 0.1-1.0, 0.1-0.5, 0.1-0.3, 0.3-5.0, 0.3-4.5, 0.3-4.0, 0.3-3.5, 0.3-3.0, 0.3-2.5, 0.3-2.0, 0.3-1.5, 0.3-1.0, 0.3-0.5, 0.5-5.0, 0.5-4.5, 0.5-4.0, 0.5-3.5, 0.5-3.0, 0.5-2.5, 0.5-2.0, 0.5-1.5, or 0.5-1.0 mg/kg body weight.

Aliquots of 50 mg/mL ethanolic solutions of cKK-E12, DOPE, Chol and DMG-PEG2K were mixed in a molar ratio of 40:30:25:5 and diluted with ethanol to 3 mL final volume. Separately, an aqueous buffered solution (10 mM citrate/150 mM NaCl, pH 4.5) of FIX, ASS1, or FFL mRNA was prepared from a 1 mg/mL stock. The lipid solution was injected rapidly into the aqueous mRNA solution and shaken to yield a final suspension in 20% ethanol. The resulting nanoparticle suspension was filtered, diafiltrated with 1×PBS (pH 7.4), concentrated and stored at 2-8° C. The final concentration of FIX mRNA was approximately 0.77 mg/mL FIX mRNA (encapsulated), Z_(ave)=76 nm, PDI=0.08. The final concentration of ASS1 mRNA was approximately 0.64 mg/mL ASS1 mRNA (encapsulated), Z_(ave)=78 nm (Dv(50)=46 nm; Dv(90)=96 nm). The final concentration of FFL mRNA was approximately 1.31 mg/mL FFL mRNA (encapsulated), Z_(ave)=75 nm, PDI—0.11. The final concentration of SMN mRNA was approximately 1.85 mg/mL SMN mRNA (encapsulated). Average particle size (Z_(ave))=71 nm, (particle size for 50% of particles was 44 nm or less (Dv(50))=44 nm; and the particle size for 90% of the particles was 93n or less (Dv(90)=93 nm)).

Example 2. Administration of mRNA-Loaded Liposome Nanoparticles

This example illustrates exemplary methods of administering mRNA-loaded liposome nanoparticles and methods for analyzing delivered mRNA and subsequently expressed protein in various target tissues in vivo.

All studies were performed using male CD-1 mice of approximately 6-8 weeks of age at the beginning of each experiment. Samples were introduced by a single bolus tail-vein injection of an equivalent total dose of 1.0 mg/kg (or otherwise specified) of encapsulated FIX, FFL or ASS1 mRNA. Mice were sacrificed and perfused with saline at the designated time points.

Various organ tissues such as the liver, spleen, kidney and heart of each mouse was harvested, apportioned into separate parts, and stored in either 10% neutral buffered formalin or snap-frozen and stored at −80° C. for analysis.

All animals were euthanized by CO₂ asphyxiation at designated time points post dose administration (±5%) followed by thoracotomy and terminal cardiac blood collection. Whole blood (maximal obtainable volume) was collected via cardiac puncture on euthanized animals into serum separator tubes, allowed to clot at room temperature for at least 30 minutes, centrifuged at 22° C.±5° C. at 9300 g for 10 minutes, and the serum extracted. For interim blood collections, approximately 40-50 μL of whole blood was collected via facial vein puncture or tail snip. Samples collected from non-treatment animals were used as a baseline ASS1 levels for comparison to study animals.

Enzyme-Linked Immunosorbent Assay (ELISA) Analysis

A. Human FIX ELISA

Quantification of FIX protein was performed following procedures reported for human FIX ELISA kit (AssayMax, Assay Pro, Catalog #EF1009-1).

B. Human ASS1 ELISA

Standard ELISA procedures were followed employing mouse anti-ASS1 2D1-2E12 IgG as the capture antibody with rabbit anti-ASS1 #3285 IgG as the secondary (detection) antibody (Shire Human Genetic Therapies). Horseradish peroxidase (HRP)-conjugated goat anti-rabbit IgG was used for activation of the 3,3′,5,5′-tetramethylbenzidine (TMB) substrate solution. The reaction was quenched using 2N H2504 after 20 minutes. Detection was monitored via absorption (450 nm) on a Molecular Device SpectraMax instrument. Untreated mouse serum and organs and human ASS1 protein were used as negative and positive controls, respectively.

IVIS Bioluminometer Measurements

To visual luminescence in treated mice, several steps were followed. Anesthesia using isoflurane vaporizer at 1-3% (usually @2.5%) was initially employed. Using a microsprayer, 50 μL/animal of luciferin in PBS was administered at 60 mg/mL via intratracheal/intranasal. Luciferin was allowed to distribute for 5-10 minutes. Animals were placed in an isoflurane chamber until anesthetized. Anesthetized animals were placed into the IVIS imaging chamber at dorsal recumbency and positioned into the manifold. Pictures of mice were taken. In these Examples, the acquisition settings providing highest sensitivity were: camera height at D level, F/Stop at f1, binning at high resolution, and exposure time at 5 minutes. Exposures were repeated up to 3 times (5, 10 and 15 minutes post Luciferin Injection).

In Situ Hybridization (ISH) Analysis

In situ hybridization was performed using “ZZ” probe technology. Probes were generated based on codon-optimized sequence of human messenger RNA. Tissues were fixed for 24-48 hours in 10% neutral buffered formalin and embedded in paraffin. Positive detection of desired mRNA was achieved through 6 consecutive amplification steps followed by chromagenic visualization using 3,3′-diaminobenzidine (DAB). Positive signal was compared to that of untreated mouse.

Example 3. Highly Effective In Vivo Production of Therapeutic Proteins

This example demonstrates highly efficient and sustained production of proteins encoded by mRNA delivered by liposomes incorporating the cationic lipids described herein (e.g., cKK-E12) in serum and various organ tissues.

In Vivo Human FIX Protein Production Results

The production of human FIX protein via hFIX mRNA-loaded cKK-E12-based lipid nanoparticles was tested in CD-1 mice as a single, bolus intravenous injection. FIG. 1 represents the amount of human FIX protein detected via ELISA when treating mice with human FIX mRNA-loaded cKK-E12-based lipid nanoparticles as compared to a C12-200-based lipid nanoparticle encapsulating hFIX mRNA. The mice were sacrificed twenty-four hours post-injection and organs were harvested (as described above).

C12-200-based lipid nanoparticles have been shown to be an effective vehicle to deliver and express mRNA in vivo (see, PCT Application Publication NO. WO2012170930, the disclosure of which is hereby incorporated by reference). Surprisingly, as represented in FIG. 1 , cKK-E12 based lipid nanoparticles are even more effective in delivering human FIX mRNA in vivo, resulting in close to 50% higher protein expression detected in the plasma of the treated mice, as compared to C12-200-based lipid nanoparticles.

FIG. 2 shows the results of a dose-response experiment as represented by the amount of human FIX protein detected via ELISA when treating mice with human FIX mRNA-loaded cKK-E12-based lipid nanoparticles at various doses. The mice were bled at 6 hours and sacrificed twenty-four hours post-injection and organs were harvested (as described above).

A clear dose response was achieved when measuring liver levels of human FIX protein. The dosing range was from 0.10-3.0 mg/kg of encapsulated human FIX mRNA. These data demonstrate the ability of the lipid nanoparticles to efficiently deliver messenger RNA, release the payload and process this exogenous mRNA via translation to produce human FIX protein, which is then subsequently secreted into the bloodstream. Levels of human FIX protein are well above therapeutic levels (>100 ng/mL plasma) and surpass normal physiological levels (˜5 ug/mL plasma) when dosing at 1.0 mg/kg or greater. Further, the plasma residence time of this human protein is sustained through at least 24 hours post administration.

In Vivo Human ASS1 Protein Production Results

The production of human ASS1 protein via codon-optimized hASS1 mRNA-loaded cKK-E12-based lipid nanoparticles was tested in CD-1 mice as a single, bolus intravenous injection. FIG. 3 represents the amount of human ASS1 protein detected via ELISA when treating mice with human ASS1 mRNA-loaded cKK-E12-based lipid nanoparticles at various doses. The mice were sacrificed twenty-four hours post-injection and organs were harvested (as described above).

A clear dose response was achieved when measuring liver levels of human ASS1 protein. As shown in Table 5, the dosing range was from 0.10-2.0 mg/kg of encapsulated human ASS1 mRNA in cKK-E12 lipid nanoparticles. These data demonstrate the ability of the lipid nanoparticles to accumulate in the liver and release the mRNA payload and the liver to process this exogenous mRNA via translation to produce human ASS1 protein.

TABLE 5 Raw values of human ASS1 protein as measured via ELISA analysis (as depicted in FIG. 1). Codon-optimized human ASS1 mRNA was delivered via cKK-E12-based lipid nanoparticles. Doses are based on encapsulated ASS1 mRNA. Values are depicted as nanogram of human ASS1 protein per milligram total protein in liver. Dose Encapsulated Human ASS1 mRNA (mg/kg) ASS1 Protein (ng/mg total protein) 0.10 BLD 0.30 BLD 0.60 546 1.0 1388 2.0 3371 BLD = Below Limit of Detection for ELISA.

While the sensitivity of the ELISA has limitations at lower values, western blot analysis allows for clear visualization of the human ASS1 protein at lower doses (0.3-3.0 mg/kg) (see FIG. 4 ). FIG. 4 depicts a comparison of human ASS1 protein levels in liver as a function of dose via western blot analysis upon a single intravenous dose of human ASS1 mRNA-encapsulated cKK-E12 lipid nanoparticles. CD1 mice were sacrificed at 24 hours post-administration and livers were harvested and analyzed as described above.

To further understand the ability of ASS1 mRNA-encapsulated lipid nanoparticles to facilitate the delivery of mRNA to selected organs (liver), a pharmacokinetic analysis was performed, monitoring human ASS1 protein levels in the liver over a one week time period. FIG. 5 depicts the quantity of human ASS1 protein detected in the liver at various time points up to 7 days after administration of human ASS1-loaded lipid nanoparticles (cKK-E12). This was accomplished as a single dose (1.0 mg/kg encapsulated mRNA) given intravenously.

In this case, we observed a maximum serum level of human ASS1 protein at approximately 24-48 hours post-administration. Measurable levels of protein were still observed 1 week post-administration as determined by both ELISA and western blot (FIGS. 5 and 6 , respectively). FIG. 6 depicts a comparison of human ASS1 protein levels in liver over time via western blot analysis upon a single intravenous dose of human ASS1 mRNA-encapsulated lipid nanoparticles (1.0 mg/kg dose).

Direct detection of the active pharmaceutical ingredient (ASS1 mRNA) in the livers of the treated mice was achieved using in situ hybridization (ISH) based methods. As demonstrated in FIGS. 7 & 8 , the exogenous human ASS1 messenger RNA could be detected in high levels at the earliest time point tested (30 minutes) and the signal remained strong for 48 hours after dosing. Further, human ASS1 mRNA was still detectable 72 hours post-administration.

In addition to ISH, detection of the resulting human ASS1 protein was achieved using immunohistochemical (IHC) means. Using a mouse monoclonal antibody (02D2-2E12) for specific binding, the presence of target human ASS1 protein in the cytoplasm of hepatocytes of treated livers can be readily observed. FIG. 9 shows the immunohistochemical staining of human ASS1 protein in treated mouse livers 24 hours after administration.

In Vivo Delivery of FFL mRNA Via Nebulization

To assess whether additional routes of delivery were feasible, FFL mRNA was encapsulated in cKK-E12 liposomes and those liposomes were nebulized. As shown in FIG. 10 , it is possible to efficiently nebulize cKK-E12 based lipid nanoparticles encapsulating mRNA. FIG. 10 represents mice treated with luciferin 24 hours after exposure to nebulized FFL mRNA loaded cKK-E12 lipid nanoparticles.

Example 4. CNS Delivery of hSMN-1 mRNA

This example provides an exemplary cKK-E12 liposome formulations for effective delivery and expression of mRNA in the CNS. Specifically, the example demonstrates that delivery of human survival of motor neuron-1 (hSMN-1) mRNA into various tissues of the brain and spinal cord.

Messenger RNA Material

Codon-optimized human Survival of Motor Neuron-1 (hSMN-1) messenger RNA (see SEQ ID NO: 4) was synthesized by in vitro transcription from a plasmid DNA template encoding the gene, which was followed by the addition of a 5′ cap structure (Cap 1) (Fechter, P.; Brownlee, G. G. “Recognition of mRNA cap structures by viral and cellular proteins” J. Gen. Virology 2005, 86, 1239-1249) and a 3′ poly(A) tail of approximately 250 nucleotides in length (SEQ ID NO: 15) as determined by gel electrophoresis. The 5′ and 3′ untranslated regions present in each mRNA product are represented as X and Y, respectively and defined as stated in Example 1.

Formulation Protocol

Lipid nanoparticles (LNP) were formed via standard ethanol injection methods (Ponsa, M.; Foradada, M.; Estelrich, J. “Liposomes obtained by the ethanol injection method” Int. J. Pharm. 1993, 95, 51-56). For the various lipid components, a 50 mg/ml ethanolic stock solutions was prepared and stored at −20° C. In preparation of the cKK-E12 lipid nanoparticle formulation listed in Table 6, each indicated lipid component was added to an ethanol solution to achieve a predetermined final concentration and molar ratio, and scaled to a 3 ml final volume of ethanol. Separately, an aqueous buffered solution (10 mM citrate/150 mM NaCl, pH 4.5) of hSMN-1 mRNA was prepared from a 1 mg/ml stock. The lipid solution was injected rapidly into the aqueous mRNA solution and shaken to yield a final suspension in 20% ethanol. The resulting nanoparticle suspension was filtered and dialysed against 1×PBS (pH 7.4), concentrated and stored between 2-8° C. SMN-1 mRNA concentration was determined via the Ribogreen assay (Invitrogen). Encapsulation of mRNA was calculated by performing the Ribogreen assay with and without the presence of 0.1% Triton-X 100. Particle sizes (dynamic light scattering (DLS)) and zeta potentials were determined using a Malvern Zetasizer instrument in 1×PBS and 1 mM KCl solutions, respectively.

Intrathecal Administration of mRNA Loaded Liposome Nanoparticles

All in vivo studies were performed using either rats or mice of approximately 6-8 weeks of age at the beginning of each experiment. At the start of the experiment, each animal was anesthetized with isoflurane (1-3%, to effect) by inhalation. Once anesthetized, each animal was shaved at the exact injection site (L4-L5 or L5-L6). Following insertion of the needle, reflexive flick of the tail was used to indicate puncture of the dura and confirm intrathecal placement. Each animal received a single bolus intrathecal injection of the test formulation listed in Table 6. All animals were sacrificed 24 hours post injection and perfused with saline.

Isolation of Organ Tissues for Analysis

All animals had the whole brain and spinal cord harvested. The brain was cut longitudinally and placed in one histology cassette per animal. The whole spinal cord was stored ambient in a 15 ml tube containing 10% neutral buffered formalin (NBF) for at least 24 hours and no more than 72 hours before transfer into 70% histology grade alcohol solution. Each spinal cord sample was cut into cervical, thoracic and lumbar sections. Each spinal cord section cut in half and both halves were placed in individual cassettes per section (cervical, thoracic and lumbar) for processing. All three cassettes were embedded into one paraffin block per animal. When applicable, portions of brain and spinal cord were snap frozen and stored at −80° C.

hSMN-1 Western Blot Analysis

Standard western blot procedures were followed employing various antibodies that recognizes hSMN protein, such as: (A) anti-SMN 4F11 antibody at 1:1,000 dilution; (B) Pierce PA5-27309 a-SMN antibody at 1:1,000 dilution; and (C) LSBio C138149 a-SMN antibody at 1:1,000 dilution. For each experiment one microgram of hSMN mRNA was transfected into 1×10⁶ BHK-21 cells using Lipofectamine 2000. Cells were treated with OptiMem and harvested 16-18 hours post-transfection. Cell lysates were harvested, processed and loaded on to an 8-16% Tris Glycine gel. The gel was transferred using a PVDF membrane and treated with the respective primary antibody. Goat anti-mouse HRP antibody was used as the secondary antibody at 1:10,000 dilution for 45 minutes at room temperature followed by washing and development. The data demonstrates that each antibody tested showed a strong signal for hSMN-1 and was specific for human SMN, as indicated by an absence in a cross-reactive signal for untreated BHK cells (FIG. 11 ).

In Situ Hybridzation (ISH) Analysis

Tissue from each representative sample, was assayed for hSMN-1 mRNA using a manual in situ hybridization analysis, performed using RNAscope® (Advanced Cell Diagnostic) “ZZ” probe technology. Probes were generated based on the codon-optimized sequence of human SMN messenger RNA (SEQ ID NO: 4). Briefly, the RNAscope® assay is an in situ hybridication assay designed to visualize single RNA molecules per cell in formalin-fixed, paraffin-embedded (FFPE) tissue mounted on slides. Each embedded tissue sample was pretreated according to the manufacturers protocol and incubated with a target specific hSMN-1 RNA probe. The hSMN-1 probe was shown to be specific for human SMN-1 and had little to no cross reactivity with mouse or rat SMN-1. Once bound, the hSMN-1 probe is hybridized to a cascade of signal amplification molecules, through a series of 6 consecutive rounds of amplification. The sample was then treated with an HRP-labeled probe specific to the signal amplification cassette and assayed by chromatic visualization using 3,3′-diaminobenzidine (DAB). A probe specific for Ubiquitin C was used as the positive control. Positive SMN signal was compared to that of untreated and vehicle control treated rat or mouse tissue. Stained samples were visualized under a standard bright field microscope.

Immunohistochemical Analysis

Human SMN-1 mRNA-loaded lipid nanoparticles were administered to rats via intrathecal injection, and tissue samples collected and processed 24 hours post administration in accordance with the methods described above. Rat spinal tissue samples were then assayed for hSMN-1 protein expression. Briefly, fixed tissue embedded in paraffin was processed and placed on slides. The slides were dewaxed, rehydrated and antigen retrieval was performed using a pressure cooker with citrate buffer. Several blocking buffers were employed followed by primary antibody incubation overnight at 4° C., using the 4F11 antibody at a 1:2500 dilution. The resulting slides were washed and incubated at ambient temperature with the secondary antibody polymer followed by washing and subsequent chromagen development. The data demonstrates that in as little as 24 hours post intrathecal adminiatration of hSMN-1 mRNA, staining is observed for human SMN-1 protein when compared to no-treatment control (FIG. 13 ). This supports the previous findings which demonstrate delivery of hSMN-1 mRNA to the spinal tissue. Furthermore, the data demonstrates that once delivered to the cell hSMN-1 mRNA is effectively expressed to generate hSMN-1 protein.

Results

The data presented in this example demonstrates that intrathecal administration of hSMN-1 mRNA loaded liposomes (e.g., lipid or polymer-based nanoparticles) results in successful intracellular delivery of mRNA in neurons in the brain and spinal cord, including those difficult to treat cells, such as anterior horn cells and dorsal root ganglia.

The results have shown that mRNA encapsulated within a lipid nanoparticle (e.g., lipid nanoparticle comprising cKK-E12) can be effectively delivered to various tissues of the CNS following intrathecal administrations. Using the exemplary formulation disclosed in Table 6, mRNA was effectively delivered and internalized within various neurons of the spinal cord (FIGS. 12A-12C), as verified by in situ hybridization assay. Surprisingly, intracellular mRNA delivery was demonstrated in the difficult to reach neuronal cells of the anterior horn, located deep within the tissues of the spinal column (FIGS. 12A-12C). Little to no background was observed with mouse or rat SMN-1, indicating specificity for the human SMN-1 probe. Positive SMN signal was compared to that of untreated and vehicle control treated rat or mouse tissue. Stained samples were visualized under a standard bright field microscope.

These data demonstrates that the lipid or polymer nanoparticle based mRNA delivery approach described herein was able to successfully permeate the complex and dense cell membrane of the spinal cord neurons and deliver the mRNA payload for the production of encoded proteins inside neurons. It was particularly surprising that the mRNA delivery approach described herein was equally successful in permeating difficult to treat neurons such as anterior horn cell and dorsal root ganglia. Thus, the data presented herein demonstrates that lipid or polymer nanoparticles, such as those comprising cKK-E12, may serve as a promising option for delivering mRNA to neuronal cells in the treatment of a CNS disease. In particular, the present example demonstrates that hSMN mRNA loaded nanoparticles can be effectively delivered to neurons, including those difficult to treat motor neurons in the spinal cord, and can be used for the production of SMN protein and treatment of spinal muscular atrophy.

Example 5. In Vivo CO-CFTR-C-His₁₀ mRNA Delivery to CFTR Knockout Mice

Messenger RNA Synthesis. For the experiment, C-terminal His₁₀ tagged codon-optimized human cystic fibrosis transmembrane conductance regulator (CO-CFTR-C-His₁₀) (SEQ ID NO:8) (“His₁₀” disclosed as SEQ ID NO: 11) and non-tagged codon-optimized human CFTR (CO-CFTR) (SEQ ID NO:9) mRNA were synthesized by in vitro transcription from a plasmid DNA template using standard method. mRNAs used in this example and Example 6 were produced by IVT in which 25% of U residues were 2-thio-uridine and 25% of C residues were 5-methylcytidine.

Analysis of human CFTR protein produced via intratracheal administered mRNA-loaded nanoparticles. For the study, CFTR knockout mice were used. CFTR mRNA formulation or vehicle control was introduced using a PARI Boy jet nebulizer. Mice were sacrificed and perfused with saline, after a predetermined period of time, to allow for protein expression from the mRNA.

PEI Formulation. PEI formulation has been used to deliver CFTR mRNA to the lung and was used as a control in this experiment. Polymeric nanoparticle formulations with 25 kDa branched PEI were prepared as follows. The required amount of mRNA was diluted just before application in water for injection (Braun, Melsungen) to a total volume of 4 ml and added quickly to 4 ml of an aqueous solution of branched PEI 25 kDa using a pipette at an N/P ratio of 10. The solution was mixed by pipetting up and down ten times and nebulized as two separate 4.0 ml fractions one after another to the mouse lungs using the indicated nebulizer.

cKK-E12 Formulation. For the lipid-based nanoparticle experiment, a lipid formulation was created using CO-CFTR-C-His₁₀ RNA in a formulation of cKK-E12:DOPE:Chol:PEGDMG2K (relative amounts 50:25:20:5 (mg:mg:mg:mg)). The solution was nebulized to the mouse lungs using the indicated nebulizer.

Nebulization (Aerosol) Administration of Human CO-CFTR-C-His₁₀ mRNA. CFTR test materials were administered by a single aerosol inhalation via PARI Boy jet nebulizer (nominal dose volume of up to 8 mL/group). The test material was delivered to a box containing the whole group of animals (n=4) and connected to oxygen flow and scavenger system.

Administration of Human CO-CFTR-C-His₁₀ mRNA. CFTR mRNA was prepared in the manner described above. Four CFTR knockout mice were placed in an aerosol chamber box and exposed to 2 mg total codon optimized unmodified human CFTR mRNA (comprising the coding sequence of SEQ ID NO: 8) via nebulization (Pari Boy jet nebulizer) over the course of approximately one hour. Mice were sacrificed 24 hours post-exposure.

Euthanasia. Animals were euthanized by CO₂ asphyxiation at representative times post-dose administration (±5%) followed by thoracotomy and exsanguinations. Whole blood (maximal obtainable volume) was collected via cardiac puncture and discarded.

Perfusion. Following exsanguination, all animals underwent cardiac perfusion with saline. In brief, whole body intracardiac perfusion was performed by inserting 23/21 gauge needle attached to 10 mL syringe containing saline set into the lumen of the left ventricle for perfusion. The right atrium was incised to provide a drainage outlet for perfusate. Gentle and steady pressure was applied to the plunger to perfuse the animal after the needle had been positioned in the heart. Adequate flow of the flushing solution was ensured when the exiting perfusate flows clear (free of visible blood) indicating that the flushing solution has saturated the body and the procedure was complete.

Tissue Collection. Following perfusion, all animals had their lungs (right and left) harvested. Both (right and left) lungs were snap frozen in liquid nitrogen and stored separately at nominally −70° C.

Expression of human CFTR in CO-CFTR-C-His₁₀ in CFTR knockout mice. CFTR expression was detected by Western blot analysis of tissue lysate collected from CFTR mRNA-treated mouse lungs. Mature “C” band was detected in left and right lungs of all treated mice, for both the cKK-E12-based and PEI-based formulations (FIG. 14 ). Expression of the mature “C” band was verified by comparison with lysate collected from HEK 293T human CO-CFTR-C-His₁₀ positive cells. In contrast, no detectable signal was observed in lysate collected from wild type untreated control mice (FIG. 14 ). Taken together, these data suggest that cKK-E12 may be used to deliver mRNA (e.g., CFTR mRNA) to the lung via, e.g., inhalation, as effectively as or even better than PEI based formulations.

Example 6: In Vivo Expression in the Lung

This example further desmonstrates successful in vivo expression in the lung following aerosol delivery of mRNA-loaded ckk-E12 based nanoparticles. All studies were performed using pigs of the German Landrace, obtained from Technical University Munich, Weihenstephan, Germany. The pigs had a body weight ranging from 35-90 kg. FFL/CO-CFTR-C-His10 mRNA formulation or vehicle control was introduced using a Pari jet nebulizer. Pigs were sacrificed and perfused with saline, after a predetermined period of time, to allow for protein expression from the mRNA.

Messenger RNA Synthesis. In the example, codon optimized fire fly luciferase (CO-FFL) mRNA was synthesized by in vitro transcription from plasmid DNA templates.

cKK-E12 Formulation. For the lipid-based nanoparticle experiment, a lipid formulation was created using 1 mg FFL+9 mg of CO-CFTR-C-His₁₀ mRNA encapsulated in a formulation of cKK-E12:DOPE:Chol:PEGDMG2K (relative amounts 40:30:25:5 (mol ratio). The solution was nebulized to the Pig lungs using the indicated nebulizer.

Aerosol Application. The aerosol (Saline or CO-FFL cKK-E12 formulation) was nebulized and inhaled into the anaesthetized pig. Sedation in pigs was initiated by premedication with azaperone 2 mg/kg body weight, ketamine 15 mg/kg body weight, atropine 0.1 mg/kg body weight and followed by insertion of an intravenous line to the lateral auricular vein. Pigs were anesthetized by intravenous injection of propofol 3-5 mg/kg body weight as required. Anesthesia was maintained by isoflurane (2-3%) with 1% propofol bolus injection at 4 to 8 mg/kg body weight to enhance anesthesia as required. Duration of the anesthesia was approximately 1-3 hrs. Pigs were killed with bolus injection of pentobarbital (100 mg/kg body weight) and potassium chloride via the lateral ear vein. Lungs were excised and tissue specimens were collected from various lung regions followed by incubation in cell culture medium overnight. The stored samples were subjected to bioluminescence detection.

Bioluminescence Analysis. For measurement of luciferase activity, tissue specimens were either homogenized and analyzed in a tube luminometer or incubated in a medium bath comprising D-Luciferin substrate and subjected to ex vivo luciferase BLI. The data illustrate that a strong bioluminescence signal was observed for each of the (A)CO-FFL/CO-CFTR-C-His₁₀ mRNA treated pigs, when compared to (B) control lung tissue samples from control pigs (Saline vehicle control) (FIGS. 15 A&B).

These data illustrate that FFL/CFTR mRNA were successfully delivered to and expressed in the lung by aerosol administration of a cKK-E12 based lipid formulation.
